摘要:
The invention relates to a tensioner (1) for a traction drive with a rotationally fixed housing (2) to a side of which a rotatable swivel arm (10), provided with a rotatable tension roller, is associated. A torsion spring (7) is placed between the housing (2) and the swivel arm (10) for loading the swivel arm (10) in the direction of an end position. Support of the tension spring (7) is realized by an insert (17a) placed in a circular ring shaped space (16) radially defined by a housing portion and the torsion spring (7).

An arrangement for closing an opening in a vehicle and method for producing such an arrangement. In an arrangement for closing an opening in a vehicle, comprising a pane and an anti-shatter film attached to the pane, in the border region of the pane, the pane and the anti-shatter file are provided with a foam encapsulation. The foam encapsulation is arranged at least particularly spaced apart from an edge of the anti-shatter film, which edge is formed on the pane.

In a motor vehicle with a roof opening (12) located in a fixed roof surface (10) and a cover (13) for closing the roof opening, the cover has an at least partially transparent pane (14) and a frame which is connected to the pane and which extends over at least one part of the edge of the pane. The pane (14) is a plastic pane and the frame is formed by in situ foaming (20) of a foam material onto the periphery of the pane, the shape of the pane, in at least one partial area of a connecting region between the pane and the peripheral foam, is configured such that a permanent mechanical, positive interlocking connection is created between the pane and the peripheral foam.

The invention relates to a method for preparing metal workpieces for cold forming by first applying a phosphate layer and then applying a lubricant layer which has a major content in organic polymer material. The phosphate layer is formed by an aqueous acidic phosphating solution having a major content in calcium, magnesium or manganese and phosphate. The lubricant layer is formed by contacting the phosphated surface with an aqueous lubricant composition which has a content in organic polymer material based on ionomer and optionally also non-ionomer the organic polymer material used predominantly being monomers, oligomers, co-oligomers, polymers or copolymers based on ionomer, acrylic acid/methacrylic acid, epoxide, ethylene, polyamide, propylene, styrene, urethane, the ester or salt thereof. The invention also relates to the corresponding lubricant composition, to the lubricant layer produced thereof and to its use.

A dosing device is provided and comprises a withdrawal container and a dosing means comprising at least one dosing unit which is a piston-cylinder unit designed as a disposable member. The piston-cylinder unit discharges into a receiving container and valve means is provided to control flow into and out of the piston-cylinder unit.
摘要:
A metering device for liquids, especially for viscous liquids, preferably liquids which are to be metered under sterile conditions, with a plurality of metering pumps which can be simultaneously actuated. To achieve an optimized mode of operation, it is provided that the surfaces on the bottom of the pump holding plate and the top of the metering channel plate are made as adjoining sealing surfaces, forming a seal, that, in the pump holding plate, there is a bypass channel with outlet openings in the sealing surface on the bottom of the pump holding plate for each metering pump and that by the relative displacement of the pump holding plate and the metering channel plate with respect to one another, the outlet openings of the bypass channel can be moved into a position in which the bypass channel connects the respective metering channel to the respective supply channel in the metering channel plate. In this position, the respective outlet opening is also connected to the metering channel or the supply channel so that overall flushing is possible.
摘要:
A tensioner for a power transmission element of a traction drive, includes a housing, a swivel arm having a free end for connection to a rotatable tension roller which rests on the power transmission element, and a swivel bearing, including an axle for connection to the swivel arm and a bushing forming part of the housing and supporting the axle, for rotatably supporting the swivel arm in the housing. A spring is positioned in a peripheral zone of the swivel bearing between the swivel arm and the housing. Mounted in fixed rotative engagement to the axle and supported by the housing via a friction lining is a friction disk, with a disk-shaped first dampening element positioned between the friction lining and the housing.

A linear induction motor, particularly for levitation-type vehicles (e.g., magnetic-suspension vehicles), has a stator juxtaposed with a reaction rail and formed with a plurality of longitudinally spaced windings or coils interdigitated with damping bars forming a damping cage with a pair of longitudinal conductors flanking the stator core. The latter is constituted by a lamination stack and is formed, in the region facing the reaction rail, with a plurality of slots in which portions of the coils are received. The slots increase in depth outwardly and the coils have portions which progressively recede from the reaction rail outwardly.
